To @ZZ whom t may concern:

Be it known that We, MAX RUMPF and WiLLmirE. Niuz, citizensof the United States, residing at,Cl iicago,-in the county of Cook and `State of Illinois, have invented certain new and useful Improvements in Hand Stamps, of which the following is a speciiication, reference being had to the accompanying thereof.

Thepurpose of this invention is to provide an improved constructionof a hand- Y operated stamp carrying Va'plurality of Figure 3, showing the parts at printing printing elements and adapted to be adjust-,

ed to bring lany selected printing space into printing position, a specific purpose of the invention being to provide improved means for selecting and setting at printing position the desired printing face. It consists of the elements and features of construction shown and described as indicated in the claims.

In the drawings Figure 1 is a top plan view on areduced scale of a stamp embodying this invention.

In the construction shown-,in-,thefdra'rvf ings, A isa frame o'rstandardA comprising" a crosshead,1, and uprights, 2, 2. "B isa plun ger comprising a stem, B1, vWhich has abea'ring at a, in the cross-head of the standard,V

A., and which itself comprises a cross-head, 5, sectoral side limbs, 6, 6, and a cylindrical segmental web, 7, which constitutes What? may be called a key-board for the operatingl f buttons of certain manually operable keys,- hereinafter described, for setting the stamp carrying rotor at selectedpositions for.' pre senting the desired 'printing 'facev inl print-' ing position. Theplunger is guided in the standards by means of the ends, i9, of the sha-ft, 9, constituting trunnions engaging the vertically extending slots, al, al, inthe uprights, 2, '2, of the standard. The shaft, 9, extends through both limbs','6, 6, ofthe plunger, and maybe either loose or fast inl these limbs, but in either event," it `is 'longitudinally checked and nretained in Y' the onto its protruding ends outside of the uprights, 2, 2, of the standard. 0n the shaft, 9, between the limbs, 6, 6, of the plunger, there is mounted for rotation the rotor, C, which is polygonal in transaxial section, having parallelogramlnatic faces suitably provided with means for holding interchangeable or removable stamping or printing plates, 15. For mounting the rotor on the shaft, it has itself a hollow shaft, comprising the two members, 14: and 15, interlocked with each other by the tongues, lila, of the part, 14, which engage notches in the part, 15a. One head, 17, of the rotor is secured to the shaft member, 15a, by abutting against and being secured to a collar, 15b, made fast on said member, 15a. The other head, 17 a, of the rotor has a central depression forming a spring chamber, 17C, for accommodating a spring, 18, provided for a purpose hereinafter explained, and is secured to the hollow shaft member, 14:, by riveting onto the end of the latter as seen at 17. The inner diameter of the part, 14, is adapted for journaling upon the shaft,9. At the opposite endof the rot-or shaft member, 15a, there is telescoped within it and made fast to it, operating as a bushing Iwithin it and affording it journal bearing on the shaft, 9, a sleeve hub, 19a, of the pinion, 19, between which pinion and proximate end of the shaft member, 15a, there is interposed a spacing washer or collar, 20. The pinion, 19, is thus made rigid with the rotor. D is a rocker comprising [a cylindrical segment web, 25, having sectoral radius arms, 25a and 25h, by which said rocker is mounted for rocking about the shaft, 9, and coaxially with the rotor, C. One of said sectoral radius arms, 25a, is journaled directly upon the shaft, 9, and the other, 25'), is journaled upon the opposite end of the rotor shaft member, 15a, between the head, 17, of the rotor and the spacing washer or collar, 20, a spacing washer, 20a, being interposed between said radius arm and the collar, 15b, of the rotor head. Upon the left-hand sectoral radius arm, 25h, there is provided a, segment rack, 26, in the plane of the pinion, 19; and upon the left-hand side limb, 6, of the plunger there is journaled a gear, 27, which meshes with the rack, 26, and with said pinion, 19, for rotating the pinion by the rocking of the rocker, D, about the shaft. The arc of the segment member, 25, and of the rack, 26, and the angle through which said rocker may rock are calculated with respect to the pinion, 19, so that the rocking of the segment through the angle provided for will give the pinion, 19, and thereby the rotor, C, one complete revolution; and thereby brought to printing position. As a matter of fact, as most conveniently, and therefore preferably, constructed, the driving action proceeds from the pinion to the gear through the segment rack rather than in the reverse direction; but this is immaterial for the result. The preferable connection of the spring is as shown, that its inner end is attached to a pin, 35, which projects from the adjacent radius arm, 25, of the rocker, D, and its outer end is hooked into the circum- 'ferential wall of the depression, 17C, in the right-hand head of the rotor, @,at 17 b. The parts thus geared together,-that is, the rotor, C, and the rocking segment member, D, are locked at what may be called the normal position,-with printing plate No. 1, of the rotor in printing position,-against the reaction of the spring tending to rock the rocker, D, and rotate the rotor away from that position, by means of a dog engaging a stop abutment, d, on the right-hand radius arm, 25, of said rocker, D. The dog consists of the right-hand wing or arm, 29a, of a member which is mounted for rocking on the plunger', consisting of a bar, 29, having at its opposite ends, folded at right angles to it, forming wings, 29a and 29h, which are pivoted respectively on the two opposite limbs, 6, 6, of the plunger, as seen at 29d, the right-hand wing being deflected as seen at 29e, and having its extremity turned inward parallel to the shaft aXis forming a nose, 29", for encounter with the stop, d, as stated. A spring, 30, attached at one end to the arm, 29a, stretched to engage a pin, 30a, on the plunger limb, 6, tends to hold the nose, 29C, of the dog, 29a, in position for encounter and engagement with the stop, CZ.

It will be seen that upon depressing the bar, 29, causing disengagement of the dog, 29a, from the stop, CZ, the reaction of the spring, 18, will tend to rock the rocker, D, and rotate the rotor, C, through an angle determined by the point at which the rocking movement of the rocker, D, is arrested. For

arresting this rocking movement at the different positions corresponding to the printing position of the several printing faces of the rotor, there are provided a plurality of keys, 40, one for each printing face of the rotor except face No. 1 said keys being sprung bars secured at one end to the inner face of the segment web, 7,-called the keyboard,-of the plunger and extended around under said segment web in the direction of rotation or rocking of the rocker, D. Each of said keys has its free extremities bent inward radially with respect to the rotor and rocker; and the segment web, 25, of the rocker has a correspondingplurality of slots, 25d, all terminating at the same line parallel to the aXis at which the radially in-bent terminals, l10n, of the keys, 40, stand, and eX- tending back from said point through arcs corresponding or proportionate to the angularv movement of the rotor necessary to bring the several printing faces respectively, to printing position. Each of the keys, 40, has

an i 'operating -button, 4l, extending in through the segment web, 7, `constituting the keyfboard, said key vbuttons being arranged staggered in two rows; all the keys, 40, ex-

tend across the bar, 29, of the member which comprises the dog, 29a; and it Will be seen that upon the depression of any key, said dog Will be disengaged from' the stop, (Z. At the same time the iii-turned end, llo, of the key is inserted in the slot correspondingv to that key in the lsegment Web, 25, and the length of the slot therefore limits the angular lrocking.movement of the rocker, D, which Will -resultxfrom the release of the dog, 29". According to thel key selected for.

lfor retaining` the keyLdepressed until the rocker, D, is rocked backto itsnorm'al position.v This is' accomplished by 'furnishing the downturnedend, 40?, of the key bar, with' the T-cross, shown at Lila, and enlarging the ,Y slot opening seen at25'0,V to admit the cross ofthe T vfhiclrengages under t of the slot' and retains the vkey depressed until the rocker'is again rocked back to the,

position at which the key vWasentered, and at which it may escape through the enlargement, 25C. I

Forv returning the rocker, D, to normal position after the-stamp has Ybeen operated to imprint with the face which hask been Vset at printing position, thereY is provided on the standard at one side a vertical rack, 50; and mounted forrocking over lthe shaft, 9', therevis a member which comprises a gear segment, 51,'and -a radius arm, 52, the gear segment meshingwith the rack, 50, and the radius arm extending up alongside the righthand radiusarm of the rocker,D, carrying at its upper end a latch, 53, which has a radius arm, 5a, connected by'a Astretched spring, 55, with a pin, 5G, on the radius arm, 52,v operating to hold the latch With said arm, 54, stoppedV against a pin, 58, on the arm, ofthe segment. The latch` is carried by the radius'arm', 52, alongside the radius arm, 25a, of the rocking member, D, and having a" catchl nose, 53a, adapted lto snap into engagement With an abutment, 25?, which projeots from the said radius arm, 25, of theV rocker, D. "This abutment is positioned so, that in the eXtreme position to Vwhich the rocker, D, ma y be rocked away' ne margins j from normal positionV-'tojbring the'prin'tl ing face, 9D', into printing position, the catch nose, 53a, would be carried past it by the rocking movement Which theradius arm, 52,

said printing stroke being greater las, the rocking angle of the rocker, D, is less for bringing any ofV the'lo-Wer numbered print! ing faces to printingjposition. llt vvilll be seen, therefore, fthat in the retracting'movement of the plunger, after the; printing stroke, causing the radius arm, 52, carrying SO the dog, 58, to bev rockedfback, the catch nose, 53a, will pick up the abutment, 252 and Will rock the rocker, D, backto normal'y position. The parts-engagedV inl this operation are so positioned relatively that in fact" the retracting movementV of thel plunger rocks the rocker, -D, back Aav little past the normal' position; but in passing this' normal position the cross end, il?, of the key which` was depressed for setting'the roto-r,C,-vvill fly upthroughl theenlarged portion, 25C, of

the slot, 25d, and thereby 'thefdogg 2922`-Willv be released as the key is retracted to its normal position, the stop, ,being' rocked back past thel rearl'end, 299,", of fsaiddog. In the concluding portion of 'said reverse rocking vmovementl the wheel, 53h, of thef latch, 53, encounters an abutment, V'53, onY the plunger, positioned so that s uch encounterthe latch is rocked aboutits pivot and dis-V engaged' from Vthe abutment,v 25, onv therocker, D, whereupon the latter is rocked forward by the spring, 18, 'until the stop, (Z, encounters the end, 29, of the dog, 29a.;

and at this Vposition` it Will be seen' thatr the spring', 18, Will fhave beenv retensionedready for its proper function of actuating'- the rocker, D, andY rotating the/rotor, and the latch, 53, will be held inthe position shown in Figure 3. y y j 1w I For inking theprintingface which has been set at printing vposition` lthere is provided an ink-pad carrier, E, ycarried by the trunnions, 9a, the side arms, ,60, of said'ink pad carrier beingslotted as seen vat 60?, for' limited vertical movement of the pad carrier with respect to the printinglface. For oar* rying ,thev pad carriery atacertainl part of the operation the standard has onfeaeh limb a laterally projecting arm, 2d,'and in the end of said arms there is mounted a rockshaft,

A70having leverarms', 7l, which extend in curved direction down and in toward the standard, and have cam slots, 72, which engaffe studs. 60C, which ljroiectinward from i t: l f f 81, for engagement l of the vtrunnion, 9a.

These cam members, 80, 'are each extended outwardly from their pivots in an arm, 83, to which is connected one end of a spring, 85, which is coiled around'the shaft, 70, the other end of the spring being engaged with the lever arm, 71, so that said springs react for lifting the ends of said arms, and thereby upholding the ink-pad-carrier to the limit of the slot, 60, by which the ink pad carrier is suspended on the trunnion. At the position of rest of the parts,-that is,

with the plunger at its high positioin-the` cam slot, 81, at its upper end substantially coincides with the upper end of the vertical slot, a', in the standard upright, and extends obliquely thence down away from the side at which the arms, 71, are located. lt will be understood, therefore, that at that position, the cam members, 80, are definitely stopped at two points, viz., by their pivotal mounting on the standard and at the engagement of the said slots with the trunnions; and it will be seen, therefore, that the springs, 85, stopped on the arms, 83, operate substantially as if they were stopped on the standard, so that the springs operate to the full extent of their tensional reaction for upholding rock shaft arms, 71; and by reason of the oblique direction of the upper part ofthe camslots, 81with respect to the vertical direction in which the trunnions move' in the down-stroke of the plunger, these springs react also to up-hold the plunger to a certain limited extent, and in this respect supplement the action of theA plunger-supporting spring, B5, at the upper position in the plunger stem. rlhe cam slot, 81, has a bend about the middle of its length, as seen in Figure 15, the angular relation of its two portions above and below the bend by reason'of the position of the pivot on the cam member at one side of the vertical plane of the trunnion, is such that the lower portion is substantially vertical from the time the trunnion passes said angle in the cam slot; and it results that the plunger-upholding action of the spring', 85, supplementing that of the spring, B5, diminishes as the plunger descends and becomes substantially nothing, from the time the trunnion passes such bend in the cam slot. The purpose of this construction is to causel the plunger to be held snugly at the position of rest, without employing around the plunger stem a spring so heavy as would otherwise be necessary, which would make the finishing portion of the printing stroke, when that spring is most compressed, objectionably diiiicult.

The purpose of providing the means described for upholding the ink-pad carrier and allowing a range of movement of the plunger trunnions with respect thereto in the descending movement of the plunger, it will be understood, is to permit the rotation ofthe rotor for bringing the desired printing face into printing position without wiping or being dragged over the pad, which necessarily is in a position to have the printing face pressed upon-it for inking after said printing face has been brought to printing position. But it is also necessary that the inking pad which is held in the position described while the printing face is depressed into contact with it, should then withdraw from the printing face in order that it may afterward be swung aside without dragging o1- wiping over said printing face; and for this purpose and to provide means for swinging the printing stamp out of the path of the printing face after the inking has been effected, there is provided upon each trunnion a linkage comprising two links, 100V and 110, the former having an elongated slot by which it is hung upon the'trunnion, the latter being pivoted at its lower end to the side of the pad carrier, the two links being pivoted together at 105, a point offset from the vertical line of said two end connections. The rock shaft arm, 71, at each side has a stud, 71", which engages a cam slot, 60, in the upper part of the length of the adjacent ink pad carrier suspending arm, 60. The cam slots, 72, in the rock shaft lever arms, 71, are shaped as most clearly seen in Figures 12, 7 Sand 9, with two parts at an obtuse angle to each other. The part of the downward movement of thel ink pad carrier which occurs 0n the depression of the plunger after the stamp reaches the ink pad carrier, swings the lever arm, 71, down while the studs, 60c are traversing the initial directly transverse part of said slot, the studs being at this part 1 of the movement the actuating or driving element, and the lever arm serving by the resistance of the springs, 85, to keep the ink pad up against the stamp for inking the latter, and if the ink pad yields enough, to keep the lower end of the slot, 60C, of the ink pad carrier arm up against the trunnion, 9a. After a certain amount of depressing movement adequate for insuring the inking the stamp, it is necessary that the ink pad should descend faster than the stamp, so as to clear the latter before swinging out of the path, and thus avoid wiping and smearing the stamp; and to accomplish this is the purpose of certain details of the construction as will now be pointed out. The `upper links, 100, have each an arm, 103, which overhangs the corresponding lever arm, 71, in position to encounter said lever arm when the stud, 60C, arrives at the bend in the slot, 72; and at the point of such encounter the lever arm has its encountered edge deflected upward to form what may be called a controlling cam as seen at 71e. At this stage of the movement,that is, when theY is completed;:andfthezstamp is, inked, v[and the pfad could'be withdrawnrom-the stamp preparatory to swinging it-y asidea` But at rthis stage the trunnion, 9, isY at the lower end of the slot7 60a, in thevink-pad'fcarrier Susrate'thepad romthe'stamp.

The: oblique portion of the slot, 72, accommodates 4this movement and the continued `engagement of the stud, 60", in saidl slot, 72. At this part of the action the cam slots, 60.",
